Farm Workers Still Toil in Fields of Danger

By E.G. Vallianatos

The tale is familiar by now, but that makes it no less horrifying:
migrant men and women (most of them from Mexico and Central America),
along with some poor blacks and whites from the United States,
following the growing and harvest seasons, working hard for pitiful
wages while enduring dangerous lives.

In 1979, I was a new Environmental Protection Agency employee
attending a government-funded seminar about the plight of farm
workers. Expert after expert described conditions of horror. The
threat came from farm sprays -- the farm workers' worst enemy. Many
farm workers didn't understand the instructions on the pesticide can
or the advice of the farmers on when to enter sprayed fields.
Sometimes workers were sprayed while harvesting crops, but most often
the workers harvested crops with the toxin still on the leaves and
fruit.

More than 25 years later, little has changed.

EPA regulations address wearing proper clothing and masks to
avoid contact with the toxins, some of which are nerve poisons. But
how would one be able to wear protective clothing and masks in high
temperatures? Also, many workers carry their children in the fields,
leaving them to drink contaminated water and play in ditches drenched
with sprays.

I wrote more than one memo to senior EPA managers explaining that
the toxic exposure of farm workers during harvest put the EPA in an
awful

predicament. The agency had the responsibility to side with
workers, forbidding the use of the known toxins. But the managers
never responded to my reports -- and with good reason. They knew
things I did not. They knew that the EPA was sinking into a moral
abyss.

Scientists at Colorado State University, funded by the EPA,
confirmed in the late 1970s what knowledgeable scientists suspected
all along: Nerve-poison pesticides known as organophosphates were
affecting the central nervous systems of humans. These products of
World War II chemical warfare research, very popular with farmers,
were causing immediate and long-term crippling effects on those
coming in contact with them. Even one serious exposure could cause
lasting brain and nerve damage.

In 1981, Clarence B. Owens, an agronomy professor at Florida
A&M University, reported to the EPA and the National Science
Foundation, which had funded his research on the effects of
pesticides on migrant farm workers, that the workers were risking
their lives.

"Migrant workers are young workers," he said, "but their health
statistics resemble those of middle-age Americans. Some 56% of the
workers had abnormal kidney and liver functions; 78% had severe
chronic skin rash; and 54%, abnormalities in chest cavities."

By 1980, EPA managers had to do something about the effects of
the nerve poisons, documented by the Colorado study and, indirectly,
by the Owens study. They knew that farm workers were in continual
contact with those killer sprays. But because they dared not ban the
warfare chemicals from agriculture, they set up a fake "farm worker
protection program" to take the steam off the pressure cooker. The
EPA rejected the damning findings of Owens without any follow-up on
the deleterious effects of sprays on the migrants.

Unfortunately, farm workers continue to face physical harassment
and violence. Their wages have not changed much from the 1970s. With
rare exception, they make no money for overtime and have no right to
organize. In Florida, the Coalition of Immokalee Workers boycotted
Taco Bell for four years before they were granted, in 2005, a penny
more per pound for the tomatoes they harvest.

Farm workers, of course, deserve protection from nerve poisons.
But they are far from the only victims in this tale.

Neurotoxins on the farm or in the home are wounding all living
things. A 2006 study by Columbia University scientists made the
connection between one of those neurotoxins, chlorpyrifos, and
learning disorders in children living in New York.

EPA banned chlorpyrifos from home use in 2001, but not from
farms. What about the children in rural America?
